ARLP, is a publicly traded master limited partnership involved in the production and marketing of coal in the eastern United States with mining operations in the Illinois Basin and Appalachian coal producing regions.

We are a diversified producer and marketer of coal primarily to major United States (“U.S.”) utilities and industrial users. We began mining operations in 1971 and, since then, have grown through acquisitions and internal development to become the third-largest coal producer in the eastern U.S. At December 31, 2014, we had approximately 1.5 billion tons of coal reserves in Illinois, Indiana, Kentucky, Maryland, Pennsylvania and West Virginia. Approximately 300.7 million tons of those reserves are leased to White Oak Resources LLC (“White Oak”). For more information on White Oak, please read “Item 8. Financial Statements and Supplementary Data—Note 12. Equity Investments.” In 2014, we sold a record 39.7 million tons of coal and produced a record 40.7 million tons of coal, of which 4.0% was low-sulfur coal, 16.0% was medium-sulfur coal and 80.0% was high-sulfur coal. In 2014, we sold 95.6% of our total tons to electric utilities, of which 97.8% was sold to utility plants with installed pollution control devices. These devices, also known as scrubbers, eliminate substantially all emissions of sulfur dioxide. We classify low-sulfur coal as coal with a sulfur content of less than 1%, medium-sulfur coal as coal with a sulfur content of 1% to 2%, and high-sulfur coal as coal with a sulfur content of greater than 2%.
We operate ten underground mining complexes in Illinois, Indiana, Kentucky, Maryland and West Virginia. We also operate a coal loading terminal on the Ohio River at Mt. Vernon, Indiana. Also, we own a preferred equity interest and are making additional equity investments in White Oak and are purchasing and have funded development of coal reserves and have constructed and are operating surface facilities at White Oak’s new mining complex in southern Illinois. Our mining activities are conducted in two geographic regions commonly referred to in the coal industry as the Illinois Basin and Appalachian regions. We have grown historically, and expect to grow in the future, primarily through expansion of our operations by adding and developing mines and coal reserves in these regions.
